DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring now to the drawings and the characters of reference marked thereon, FIG. 1 illustrates a preferred embodiment of system for providing computer guided ablation of tissue, of the present invention, designated generally as 10. The system 10 includes an imaging device 12, such as ultrasound, MRI, CT, PET, SPECT, X-ray (including fluoroscope) or other suitable imaging device. The imaging device 12 receives imaging data 14 from a treatment region of a patient 16. The treatment region may be, for example, the prostate region, breast region, liver region, etc. The imaging device 12 provides imaging output data 18 to the physician or other operator 20 and imaging signals 22 to an ablative surgical computer system, designated generally as 24.

[0022] The ablative surgical computer system 24 includes a guidance module 26 for processing the imaging signals 22 and providing a treatment guidance plan 23 to the operator 20. The computer system 24 also includes a treatment module 28 for acquiring and processing surgical device output data 30, for optimally controlling treatment parameters 32 and providing feedback information 34 to the operator 20 based on the treatment guidance plan 23.

[0023] A set of surgical devices, designated generally as 36, includes at least one ablative device 38 for providing ablation of the treatment region based on the treatment parameters 32 and operator input 40. The set 36 of surgical devices also includes at least one temperature sensing device 52 for acquiring temperature data 42 from the treatment region of the patient 16. The set 36 of surgical devices provides the surgical device output data 30. A temperature sensing device output signal is provided which is a portion of the surgical device output data 30.

[0024] In a primary application of the present invention the ablative devices 38 are cryosurgical probes, as will be explained in detail below. However, it is understood that various other types of ablative devices 38 may be used in accordance with the principles of the present invention to provide the necessary ablation. The ablative devices 38 may comprise, for example, radio frequency electrodes, laser fibers, microwave catheters, high-intensity focused ultrasound, and other suitable ablative devices.

[0025] Referring now to FIG. 2 utilization of the present system with ablative devices 38, for example, cryosurgical probes, which function to ablate tissue, is illustrated, designated generally as 46. The surgical computer system 24, in present applicants' present application provides guidance as to recommended ablative element placement within a prostate 13, based on images of the prostate acquired from the imaging system, such as an ultrasound system, designated generally as 48.

[0026] The computer system 24 is programmed with software capable of: determining the dimensions of the prostate; determining the dimensions of a treatment zone; and, utilizing the determined dimensions of the prostate and treatment zone for computing the number and location of ablative elements needed to treat the treatment zone. An IBM-compatible microprocessor serves as the host computer.

[0027] The transrectal ultrasound probe 48 is used to visualize the prostate and the cryosurgical probes. A stepper assembly 50 provides the required advance. The ablative devices (e.g. cryoprobes 38) are illustrated as well as temperature probes 52. The set of surgical devices, i.e ablative devices and temperature sensing devices, are introduced through a grid (i.e. reference plate) 54.

[0028] Treatment planning preferably includes the following steps:

[0029] Step 1

[0030] Capturing Image

[0031] The live ultrasound image is displayed in the ultrasound image window.

[0032] A button entitled CAPTURE will appear at the bottom of the display.

[0033] A brachy-type grid, i.e. grid having an orthogonal reference system, should be displayed on the ultrasound image before the first image is captured.

[0034] Using the Capture window, click CAPTURE to capture the first image at the widest cross section of the prostate. Once CAPTURE is selected, the image will be frozen and displayed as a thumbnail image on the right-hand side of the screen.

[0035] You can now remove the brachy grid display for the remaining captures.

[0036] At least one image is captured. However, there is an option, for example, to capture two images at the widest portion of the prostate gland, one with the brachy grid displayed and one without it displayed, then capture additional images at the base and apex of the gland.

[0037] Step 2

[0038] Calibration

[0039] Typically, there is a calibration step.

[0040] Step 3

[0041] Outlining

[0042] You are asked to click on the four outer points of the prostate image displayed.

[0043] Start by clicking on the top edge of the prostate.

[0044] Next click on the outer most right hand side of the prostate.

[0045] Repeat this action on the bottom edge and left hand outer edge of the prostate as directed in the step 3 window text and illustrations.

[0046] When you have clicked on all four points, click the right mouse button to complete the outline.

[0047] At anytime during the outlining process, the UNDO button in the step 3 window can be selected to remove the last point placed.

[0048] When the prostate outline is completed, the system will move to the URETHRA contour mode.

[0049] To outline the urethra click on the center of the urethra and a circle will be placed.

[0050] You can adjust the urethra contour location by clicking in the center of the circle and dragging the circle to a new location holding the mouse button down.

[0051] You can adjust the size of the urethra outline by clicking on one of the four white dots displayed outside of the outline and moving it inward to reduce the size or pulling it outward to increase the size.

[0052] You must click the right mouse button to complete the urethral outline.

[0053] When the urethra outline is completed, the system will move to the RECTAL WALL contour mode.

[0054] To outline the rectal wall, click on the left top edge of the rectal wall and then click on the right top edge of the rectal wall.

[0055] You can adjust the rectal wall outline by clicking on any of the points in the outline and dragging them to a different location.

[0056] When the rectal wall outline is complete, right click to move to the next step.

[0057] Three image option:

[0058] When all outlines on the first image are complete, the system will ask you to outline the urethra on the base and apex images.

[0059] Outline the urethra in each additional image using the same method described previously.

[0060] Right click each time an outline has been completed.

[0061] Referring now to FIG. 3, a sample display screen, designated generally as 56, of the computer system 24 showing treatment planning is illustrated. The display screen 56 contains various sections. For example, a thumbnail section 58 displays thumbnail images.

[0062] Another section on the display screen 48 is the instruction box 60 that provides the user with detailed instructions at each step and makes the system easier to use. Additionally, the system has controls for specifying the patient details (name, age, etc.), calibration, adding/deleting probes and for the simulation of the ablation. The system also provides a pull down menu for switching rendering views and to toggle the display of the probe placements.

[0063] Step 4

[0064] Placing Probes

[0065] The step 4 window and suggested probe placement will appear next to the step 3 window when the outlining is complete. This window allows you to move, add or delete probes if desired.

[0066] Probe grid coordinates will also be displayed on the far right hand side of the screen.

[0067] To move a probe from the suggested probe placement, click and drag the probe points displayed on the image. This will result in the probe coordinates changing to the new location.

[0068] To add or delete probes, click the add or delete button and then click on the location on the image where you want to add a probe or click on the probe you want to delete. This will add or remove the probe to the coordinate display on the right hand side of the screen.

[0069] Once the probes are in the desired locations, click on the accept button to proceed to step 6.

[0070] Step 5

[0071] Measure

[0072] This enables the user to display key distance measurements as well as view customized measurement distances.

[0073] Step 6

[0074] TempProbe® Temperature Probe Placement

[0075] Step 6 allows the user to place TempProbes® in the desired location on the image and displays the grid coordinate points that correspond to that placement.

[0076] The user is prompted to click on the locations for the right neurovascular bundle (RNVB), left neurovascular bundle (LNVB), Apex and External Sphincter (ES) TempProbes® in the image.

[0077] For each placement the user must click on the add button in the step 6 window and then click on the location for placement in the image.

[0078] A minimum of four TempProbes® should be placed.

[0079] TempProbe® grid coordinates are displayed on the right hand side of the screen next to Cryoprobe coordinates.

[0080] The user can click on the LIVE button in the bottom right hand corner of the screen to overlay the probe placement locations and grid on top of the live ultrasound image.

[0081] The user can click on the same button that is now labeled captured images to return to the captured image display.

[0082] The user can click on the Hide Grid/Display Grid button in the bottom right hand corner of the screen to toggle the Cryogrid overlay on and off.

[0083] Although the aforementioned treatment planning and placement steps have been described with reference to a drag ball or mouse interface device, it is understood that other interface devices can be used such as touch screens, joysticks, etc.

[0084] The ultrasound probe image 48 can be seen in FIG. 3. Furthermore, parts of the anatomy can be seen, such as the urethra 62 and the rectum 64. The TempProbes® are denoted A, B, C, D and E. The cryoprobes are denoted by numeral designations 1-6. The grid being used is also shown in this display, as denoted by numeral designation 66. As noted above, the grid 66 can, optionally be deleted from the display by selecting the “hide grid” option 67.

[0085] Referring now to FIG. 4, a flow diagram for the treatment module 70, is illustrated. Once the treatment planning has been completed the treatment module 70 is used by the operator to deliver the treatment to the patient. The system provides a user interface for the operator to enter the target temperatures for the treatment of the patient. Each of the TempProbes® is therefore assigned a target temperature which is then used to determine the operation of the ablative devices.

[0086] Referring to FIG. 5, the cryoprobes and TempProbes® are displayed relative to the prostate and other anatomical structures of interest. The target temperatures for each of the TempProbes® are also displayed. The cryoprobes are numbered 1-6 in this figure. The TempProbes are designed A-D.

[0087] Referring again to FIG. 4, the step of displaying the cryoprobes and temperature probes is denoted by block 74. The ablation cycle is started based on user input (block 76). The ablation cycle is ended, based on user input (block 78) or upon reaching target temperatures.

[0088] Referring now to FIG. 6, a flow diagram of the ablation cycle is illustrated, designated generally as 80. A freeze cycle is started for a first anterior cryoprobe and a second anterior cryoprobe, i.e. probes 1 and 2 (block 82). A freeze cycle is started for a first posterior lateral cryoprobe and a second posterior lateral cryoprobe, i.e. probes 3 and 4 (block 84). A freeze cycle is started for a first posterior medial cryoprobe and a second posterior lateral cryoprobe, i.e. probes 5 and 6 (block 86). The cryoprobes are operated based on the temperature data from the temperature sensing devices, i.e. TempProbes (block 88). The operator is informed if all target temperatures have been reached (block 90). A thaw cycle is started for the cryoprobes based on operator input.

[0089] Referring now to FIG. 7a, the freeze cycle for the first anterior cryoprobe and the second anterior cryoprobe is illustrated, designated generally as 92. It involves the following steps:

[0090] a) turning on the first anterior cryoprobe and the second anterior cryoprobe (block 94);

[0091] b) determining if an anterior target temperature has been reached (block 96);

[0092] c) operating the first anterior cryoprobe and the second anterior cryoprobe at a maximum rate if an anterior target temperature has not been reached (block 98);

[0093] d) operating the first anterior cryoprobe and the second anterior cryoprobe at a substantially zero rate if an anterior target temperature has been reached (block 100); and,

[0094] e) determining if the anterior target temperature has reached substantially 0° C. (block 102). If yes, probes 3 and 4 are turned on (block 104).

[0095] Referring now to FIG. 7b, the freeze cycle for the first posterior lateral cryoprobe and the second posterior lateral cryoprobe, and for the first posterior medial cryoprobe and the second posterior lateral cryoprobe, are illustrated, designated generally as 106. These cycles involve the following steps:

[0096] a) turning on the first posterior lateral cryoprobe and the second posterior lateral cryoprobe and operating them at a maximum rate (block 108);

[0097] b) determining if a first neurovascular bundle target temperature has been reached (block 110);

[0098] c) turning off the first posterior lateral cryoprobe if the first neurovascular bundle target temperature has been reached (block 112);

[0099] d) determining if a second neurovascular bundle target temperature has been reached (block 114);

[0100] e) operating the second posterior lateral cryoprobe at a substantially zero rate if the second neurovascular bundle target temperature has been reached (block 116);

[0101] f) turning on the first posterior medial cryoprobe and the second posterior medial cryoprobe after the neurovascular TempProbes® are substantially close to their target temperatures (block 118);

[0102] g) operating the first posterior medial cryprobe and the second posterior medial cryoprobe at a power rate in a range of about 15-35%, preferably about 25% (block 124); and,

[0103] h) setting the first posterior medial cryprobe and the second posterior medial cryoprobe to a substantially zero rate (block 120) if a Denon Vieller's fascia target temperature has been reached (block 122).

[0104] Referring now to FIG. 8, an alignment assembly (also referred to as a reference plate, grid or template) is illustrated, designated generally as 54. The alignment assembly 54 utilizes an orthogonal coordinate system to position the cryoprobes and TempProbes®. Use of this alignment assembly 54 makes it possible for the cryoprobes and TempProbes® to be placed at the locations determined by the guidance module.

[0105] The cryoprobes particularly adapted for this computer guided placement are those manufactured by the present assignee, Endocare, Inc., Irvine, Calif. The urethra, which passes through the prostate, is one of the anatomic structures that usually should not be frozen during this surgery. Accordingly, the urethra is protected and kept warm with the urethral warming catheter. The bladder neck sphincter and the external sphincter are also structures that should be protected from freezing, and these are protected from freezing by the warming catheter. A transrectal probe is inserted into the rectum in order to visualize the placement of the probes and the growth of the iceballs formed by the cryoprobes. (As noted above, alternative imaging means may be utilized.) To assist in placement of the cryosurgical probes, a template 21 is used which supports the probes 22 during insertion and while they are installed in the body. The patient is placed in the lithotomic position, i.e. horizontally on an operating table with legs positioned to provide access for the ultrasound probe to be inserted into the rectum and cryoprobes to be inserted through the perineal area into the prostate.

[0106] Thus, we have described a system for assisting surgeons in performing cryosurgery of the prostate by calculating optimal positions for cryoprobes and providing display based templates for overlay over an ultrasound image display, and displaying actual cryoprobe ultrasound images together with template images so that the surgeon may compare suggested and actual placement of the probes, and adjust placement accordingly. The method and system is described above in relation to our newly enhanced CRYOCARE® cryosurgical system, which is provided with up to eight independently controlled argon powered cryoprobes. The enhanced CRYOCARE® cryosurgical system utilizes the feedback described above to provide the AutoFreeze™ functionally.

[0107] The system cools the probes to cryosurgically effective temperatures (typically below −120° C.) through Joule-Thomson cooling within the probe tips. If used for cryogenic ablation the system may be implemented with other cooling systems such as liquid nitrogen cryoprobes and mixed gas cryoprobes. The placement of probes is calculated based on this system, and the calculations may be adjusted for different systems and numbers of probes. The system may be adapted to other forms of ablation and treatment of the prostate, with adjustments in the calculations being made to account for the ablative range of the devices. Other ablative elements may include, for example, radio frequency devices, microwave devices, high intensity focused ultrasound devices, lasers, radioactive seeds and ablation agents such as chemicals, e.g. alcohol-based substances.

[0108] Although the system 10 has been described wherein the physician provides input to start and stop the ablation cycle it is understood that the treatment module may alternatively control the ablative elements automatically based upon a sensing device output signal such as, but not limited to, temperature sensing device measurements, ultrasound images of the rate of ice growth, tissue impedance measurements within the treatment zone. Such a feedback could direct the system to stop the treatment resulting in the system turning off one or more ablative elements automatically without the need for operator intervention.

[0109] Referring now to FIG. 9 an embodiment of a surgical device that comprises an integrated ablative/temperature sensing device is illustrated, designated generally as 130. The integrated ablative/temperature sensing device 130 includes a fluid supply line 132 connectable at an inlet section to a source of cryogenic fluid (not shown). A fluid connector assembly 134 is securely connected to an outlet section of the fluid supply line 132 for receiving fluid from the outlet section of the fluid supply line 132. A detachable cryosurgical probe 134 is detachably connectable to the fluid connector assembly 132. A temperature sensing device 136 is integrally attached to the ablative device, i.e. cryosurgical probe 134.

[0110] The main or longer portion of the fluid connector assembly defines a main connector assembly axis. The detachable cryosurgical probe defines a probe axis. These axes are preferably in a range of 80 degrees and 140 degrees relative to each other. Most preferably they are about 90 degrees relative to each other. Use of a right-angled system is particularly useful with computerized tomography (CT) and other image-guided (radiological) applications. Use of this cryosurgical probe system with a CT device is made easier because the detachable cryosurgical probes, fluid connector assembly, and fluid supply line can be easily contained within the confines of the CT device.

[0111] Referring now to FIG. 10, an enlarged view of the distal portion of the detachable cryosurgical probe 134 is illustrated. It can be seen that the temperature sensing device 136 comprises a cannula 138 that is securely attached to the probe 134. A thermocouple 140 is positionable within the cannula 138. The thermocouple 140 is extendible from a distal portion of the cannula 138 to project outwardly from the cannula 138 at a desired distance to provide temperature profiling. The thermocouple 140 may be formed of suitable materials, as known in this field. Examples of suitable materials include constantan and copper. The thermocouple material is coupled with a shaped memory material such as Nitinol. It projects outwardly to detect temperatures at a desired radial distance from the probe 134. This data can be used to control the freeze cycle.

[0112] Referring now to FIG. 11, an enlarged view of the distal portion of another embodiment of the detachable cryosurgical probe is illustrated, designated generally as 142. In this embodiment, the cannula 144 supports a thermocouple 146 that is straight. The FIG. 11 embodiment is less expensive to implement.

[0113] Although FIGS. 9-11 illustrate a right-angled probe, use of the detachable cryosurgical probe may be with a straight probe instead. It depends on the application. Similarly, there may be an angled non-detachable system.

[0114] A cryosurgical probe system that uses a detachable cryosurgical probe is disclosed and claimed in present applicants' co-pending patent application entitled Detachable Cryosurgical Probe, filed on Jun. 25, 2003, bearing U.S. Ser. No. 10/603,883, incorporated herein, in its entirety.
